How to test file download with Watin / IE9?
I'm trying to test file download with Watin 2.1.0 against IE9. I used the suggested code from the accepted answer to the question Downloading a file with Watin in IE9, like this:
var downloadHandler = new FileDownloadHandler(fname);
WebBrowser.Current.AddDialogHandler(downloadHandler);
link.ClickNoWait();
downloadHandler.WaitUntilFileDownloadDialogIsHandled(15);
downloadHandler.WaitUntilDownloadCompleted(200);
However, the downloadHandler.WaitUntilFileDownloadDialogIsHandled(15)
call times out. What should I do?
Solution 1:
File download dialog doesn't work in IE9 (Windows7) NetFramework 4.0.
Following code snippet might help you resolve the issue:
First you must add references UIAutomationClient and UIAutomationTypes to your test project.
After In Ie9 Tools -> View Downloads -> Options define path to your save folder.
The next method extends Browser class
public static void DownloadIEFile(this Browser browser)
{
// see information here (http://msdn.microsoft.com/en-us/library/windows/desktop/ms633515(v=vs.85).aspx)
Window windowMain = new Window(WatiN.Core.Native.Windows.NativeMethods.GetWindow(browser.hWnd, 5));
System.Windows.Automation.TreeWalker trw = new System.Windows.Automation.TreeWalker(System.Windows.Automation.Condition.TrueCondition);
System.Windows.Automation.AutomationElement mainWindow = trw.GetParent(System.Windows.Automation.AutomationElement.FromHandle(browser.hWnd));
Window windowDialog = new Window(WatiN.Core.Native.Windows.NativeMethods.GetWindow(windowMain.Hwnd, 5));
// if doesn't work try to increase sleep interval or write your own waitUntill method
Thread.Sleep(1000);
windowDialog.SetActivate();
System.Windows.Automation.AutomationElementCollection amc = System.Windows.Automation.AutomationElement.FromHandle(windowDialog.Hwnd).FindAll(System.Windows.Automation.TreeScope.Children, System.Windows.Automation.Condition.TrueCondition);
foreach (System.Windows.Automation.AutomationElement element in amc)
{
// You can use "Save ", "Open", ''Cancel', or "Close" to find necessary button Or write your own enum
if (element.Current.Name.Equals("Save"))
{
// if doesn't work try to increase sleep interval or write your own waitUntil method
// WaitUntilButtonExsist(element,100);
Thread.Sleep(1000);
System.Windows.Automation.AutomationPattern[] pats = element.GetSupportedPatterns();
// replace this foreach if you need 'Save as' with code bellow
foreach (System.Windows.Automation.AutomationPattern pat in pats)
{
// '10000' button click event id
if (pat.Id == 10000)
{
System.Windows.Automation.InvokePattern click = (System.Windows.Automation.InvokePattern)element.GetCurrentPattern(pat);
click.Invoke();
}
}
}
}
}
if you want click 'Save As' replace foreach code with this
System.Windows.Automation.AutomationElementCollection bmc = element.FindAll(System.Windows.Automation.TreeScope.Children, System.Windows.Automation.Automation.ControlViewCondition);
System.Windows.Automation.InvokePattern click1 = (System.Windows.Automation.InvokePattern)bmc[0].GetCurrentPattern(System.Windows.Automation.AutomationPattern.LookupById(10000));
click1.Invoke();
Thread.Sleep(10000);
System.Windows.Automation.AutomationElementCollection main = mainWindow.FindAll(System.Windows.Automation.TreeScope.Children
,System.Windows.Automation.Condition.TrueCondition);
foreach (System.Windows.Automation.AutomationElement el in main)
{
if (el.Current.LocalizedControlType == "menu")
{
// first array element 'Save', second array element 'Save as', third second array element 'Save and open'
System.Windows.Automation.InvokePattern clickMenu = (System.Windows.Automation.InvokePattern)
el.FindAll(System.Windows.Automation.TreeScope.Children, System.Windows.Automation.Condition.TrueCondition) [1].GetCurrentPattern(System.Windows.Automation.AutomationPattern.LookupById(10000));
clickMenu.Invoke();
//add ControlSaveDialog(mainWindow, filename) here if needed
break;
}
}
Edit: Also if you need to automate the save as dialog specifying a path and clicking save you can do it by adding this code just before break;
private static void ControlSaveDialog(System.Windows.Automation.AutomationElement mainWindow, string path)
{
//obtain the save as dialog
var saveAsDialog = mainWindow
.FindFirst(TreeScope.Descendants,
new PropertyCondition(AutomationElement.NameProperty, "Save As"));
//get the file name box
var saveAsText = saveAsDialog
.FindFirst(TreeScope.Descendants,
new AndCondition(
new PropertyCondition(AutomationElement.NameProperty, "File name:"),
new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit)))
.GetCurrentPattern(ValuePattern.Pattern) as ValuePattern;
//fill the filename box
saveAsText.SetValue(path);
Thread.Sleep(1000);
//find the save button
var saveButton =
saveAsDialog.FindFirst(TreeScope.Descendants,
new AndCondition(
new PropertyCondition(AutomationElement.NameProperty, "Save"),
new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Button)));
//invoke the button
var pattern = saveButton.GetCurrentPattern(InvokePattern.Pattern) as InvokePattern;
pattern.Invoke();
}
Solution 2:
IE9 no longer uses a dialog window for saving files. Instead, it uses the notification bar to prevent focus from being removed from the web site. See http://msdn.microsoft.com/en-us/ie/ff959805.aspx under "Download Manager" for reference.
Unfortunately, this means that the current FileDownloadHandler in WatiN will not work. It instantiates a "DialogWatcher" class per browser instance that is a basic message pump for any kind of child window. When child windows are encountered, the DialogWatcher checks to see if the window is specifically a dialog (which the notification bar is not). If it is a dialog, it then iterates over the registered IDialogHandler instances calling "CanHandleDialog." Even if the notification bar were a dialog, it is of a different Window Style (http://msdn.microsoft.com/en-us/library/windows/desktop/ms632600(v=vs.85).aspx), which is how WatiN detects the type of dialog.
From what I can see, there is no support yet for detecting the IE 9 notification bar and its prompts in WatiN. Until that support is added, you will not be able to automate downloading files in IE9.
